New Licensing APIs Since VMware vSphere 4: Check License Expiration

In my previous blog, I introduced the new licensing APIs since vSphere 4. As promised, I will write samples showing how to use the APIs.

Here is the first sample (stay tuned to next one, coming soon). What it does is to check the licenses in vCenter server for their expiration dates, and print them out in the console. You can of course save them into other format, say an CSV file so that you can use Excel to further analyze it. To run the sample, you must change the IP address to the vCenter server, the username/password, as would with most VI Java API samples.

Note that a license could be an evaluation license, whose expiration date has to be retrieved from the evaluation property. For a normal license, it’s possible that it never expires. This sample handles this case as well.
